The first synod of Rouen is generally believed to have been held by Archbishop Saint-Ouen about 650. Sixteen of its decrees, one against simony, the others on liturgical and canonical matters, are still extant.
Later synods were presided over by:
Archbishop St. Ansbert some time between 689 and 693
Archbishop Mauger in 1048

Other synods were held in 1223, 1231, 1278, 1313, 1321, 1335, 1342, 1445, and 1581. The synod held by Archbishop Jacques-Nicolas Colbert in 1699 condemned Fénelon's Maximes des Saints.
